  • Vehicle guidance device, vehicle guidance method, and vehicle guidance program
    Patent number: 8666646
    Abstract: A vehicle guidance device includes: an inter- vehicle distance specification unit that specifies an inter-vehicle distance, which is an inter-vehicle distance in a prescribed lane, between vehicles up to a reference point of a lane change; a recommended section specification unit that ,based on the specified inter-vehicle distance, specifies a recommended section in which a lane change to the prescribed lane should be made before reaching the reference point; and a communication unit that, based on the specified recommended section, outputs guidance information pertaining to the lane change to the prescribed lane.
    Type: Grant

  • Communication apparatus
    Patent number: 8035561
    Abstract: A communication apparatus communicating other apparatuses includes: a switch for switching between a vertical polarized antenna and a horizontal polarized antenna; a communication device for transmitting and receiving the electric wave via one of the antennas, which is selected by the switch; a monitor for monitoring a relative distance between the apparatus and other apparatuses; and a controller for controlling the switch such that the switch selects the vertical polarized antenna when the relative distance is equal to or larger than a distance threshold, and the switch selects the horizontal polarized antenna when the relative distance is smaller than the distance threshold. The distance threshold is larger than a distance between the apparatus and a dip point.
